Java AI Interface for Spring

[tberthel]

P:/Programme/Java/jdk1.6.0_03 but _05 is specified in the instructions?

[hoijui]

whether using jdk1.6.0_03 or _05 should not make a difference at all, as these revisions are just for bug-fixing, so you can always use the latest (though JAI worked for me with _03).

i can not help you with the stuff from infolog alone. could you please attach all the log files in Bot-libs/JAI/log, plus possibly hotspot.log (in the spring main folder)? if there is one, please send also the hs*.log.
thanks!

[hoijui]

somethign else:
i think the next version of JAI will be using the new AI C interface. i think i will have 2 interfaces, one with handleMessage, and posibly one that is quite like the current one, using the other interfaec with handleMessage behind the scenes.

[tberthel]

I did include the

Bot-libs/JAI/log

logs.

native-log.txt
native-SWIG-log.txt

were the only 2 I had.

JVM did not fail so no JVM log.

[hoijui]

as you jvm logging enabled, it should log even if the JVM does not crash, no hs*log, but hotspot.log.

did you use hoijui.jar for testing?

to be honest, i dont think i will be able to find out what is wrong :/

[tberthel]

hotspot.log is only created for the debug VM. So no it was not generated.

[tberthel]

Well I could solve the problem, but it will probably be a while since I just want to use some of my generic game AI's I developed for other games in Spring.

[tberthel]

I ran it again with the debug VM for the hotspot.log

[AF]

Please use a pastebin instead of pasting masses of text and stretching the forum out

[hoijui]

hmm... :/ does not really help either :/

2 things:
* as AF mentioned already, for log files, it would be better to use either http://www.pastebin.com or attach the files as such to your posts, not copy the text into the post, as this is bad for the forum layout.
* as the JVM seems to load ok, there may be usefull info under AI/hoijui/log (if you use hoijui.jar for testing)

if we won't find the soon, i guess its easyer to wait till the new C interface is ready, and JAI ported to it (once the interface is ready, porting should take little time). possibly it will work then for you too.

[tberthel]

Okay I have built it for 5956 and it works a little with minor hacks.

Issues:

1.

This method "bool CreateClassPath(char* classPath)" fails most of the time. I have not written c++ in a while so it was not clear to me why. Although, by replacing the body with: strcat(classPath, HACK_CLASS_PATH); it works everytime.

The HACK_CLASS_PATH is the same path used when it does work.

2. It also crashed here most of the time. I remarked this out in the "GetJNIEnv" method:

/*
for (i = 0; i < vm_args.nOptions; i++) {
delete vm_args.options.optionString;
}
delete vm_args.options;
*/

Okay with those two fixes it runs every load, but I get an Sync error and some of the commands crash. Specifically, 2,4, and 7 fail.

So I will paste bin the sync error with the hot spot. Also note before the fixes the JVM was not always loading.

I also noticed that you should use "#define SWIG_JAVA_ATTACH_CURRENT_THREAD_AS_DAEMON"

I would appreciate the SVN location of this stuff. The download page says it is in the SVN i.e., but I don't see it. I know it must be GPL since it uses GPL, but I would like to see that in the headers or a license file if your keeping it out of SVN.

Sync Error I get:

Sync warning: FPUCW 0x027F instead of 0x003A or 0x003F ("CGame::SimFrame")

[tberthel]

NVM on the post bin. Since it is the same thing over and over.

[hoijui]

Wow, nice!
thanks for that!
rightnow, i have no access to the code, but i will check some things when back home, especially about

Code: Select all

#define SWIG_JAVA_ATTACH_CURRENT_THREAD_AS_DAEMON

there is no JAI source on the SVN, as i do not have write access to it, and it is also still not very stable, as you saw

i will check the class-path stuff as well. what i did not understand, is what you mean with commands 2, 4 and 7. you mean Commandwith id=7 eg?

i already changed this part of the code:

Code: Select all

        for (i = 0; i < vm_args.nOptions; i++) {
            delete vm_args.options[i].optionString;
        }
        delete vm_args.options;

cause itis not compatible with MinGW 4.

this leads us to the last thing, the sync error you get.
which OS and compiler do you use?
if you use MinGW 3 to compile JAI, and use spring from the buildbot (Which uses MinGW 4.2.1), this would explain the sync error.

we do not yet have a working description online of how to setup MinGW 4 on windows, to compile spring. on linux it is rather easy, to cross compile for windows (buildbot also cross-compiles on linux).

all these issues should vanish, once we have the new C AI interface working, as it should not matter anymore which compiler you use to compile JAI (or any other AI).

i will check everything on monday.

[tberthel]

I was referring to the message commands to get the test AI to do something.

I am using MinGW 5.1.4 and, I also built Spring with it as well. Obviously. That could be a problem. I guess I should use MinGW 4.2.1. Were did you get the info on the auto build version. That should be on both build pages.

I usually only write Java now days, and I had steered away from MinGW and SCONS for a long time. I couldn't resist a Java AI link into Spring. Well anyways I used this for the build:

Vista and gcc version 3.4.5 (mingw-vista special r3)

Well you didn't say anything about the licensing. So I can't do anything until it is in SVN or a license file saying it is open.

[tberthel]

Also, is the auto build using 3.4.5 gcc?

[hoijui]

The auto build of spring uses 4.2.1, there is no auto build of JAI, but my release was compiled with 3.4.5. So far, i always tested JAI with 3.4.5 (i also compiled spring with that) -> i did the same like you. if you compile JAI and spring with the same MinGW/gcc, it should not get sync errors.

About the licence: Sorry, am new to open source and did forget/not care about that so far. I though i would not put a licence until it is well usable, and then i would integrate it into spring main SVN. I could setup a project page with SVN, but i would prefer to port it to the C interface before doing big changes. i also don't really recommend doing an AI with it already, as it may change some after the port.

for small things: you can send them to me (by PM) also.
is it ok like this? or any other suggestion?

[tberthel]

When you get headers that have license info or a license file I could contribute. Until then I will wait. Getting it into the SVN would speed up the development.

[tberthel]

Is this in SVN now?

[hoijui]

Not yet, but i started working on the Java interface wrapper of the C interface a few days ago. As soon as I have something at least remotely testable, i will put it on SVN with a NullJavaAI for testing. I hope this to happen in the upcomming week. The first test will be witout callback (as this will be a lot of work to wrap).

[hoijui]

If you have not yet read the AI Interface redesign topic, you may do so now:
viewtopic.php?f=15&t=15019&p=321227#p321227

Get the branch:
https://spring.clan-sy.com/svn/spring/b ... iinterface

I hope some of you will help with testing. if you are mainly interested in the Java interface, you may want to have a look at NullOOJavaAI (NullJavaAI will not be interesting for you). please do not start writing your AI yet, but give feedback about the interface in general:

• the (class-)structure of/behind OOAICallback: what would you change, how, and why?
• is this way of handling AIEvents ok? (AI Events are messages from the engine to the AI)
• ... what about AICommands? (messages from AI to engine that alter the engines state (in contrary to the methods reachable through OOAICallback))

ask here for help, if something is not working.
